COAL-HOPPER FOR GAS-RETORT CHARGERS.

SPECIFICATION forming part of Letters Patent No. 687, 600, dated November 26, 1901.

Application filed September 14, 1900. Serial No. 30,008. (No model.)

Tc aZZ whom it may concern.-

Be it known that I, GASTON A. BRONDEB, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Coal- Hoppers, of which the following is a speci fication.

The object of this invention is the production of a hopper capable of carrying a large quantity of coal which can be easily discharged by means of chutes constituting part of said hopper.

Figure 1 represents a vertical section of my hopper, taken on the line a: of Fig. 3. Fig. 1 shows a fragmentary section of Fig. 1 on line 8. Fig. 1 shows a fragmentary section of Fig. 1 on line i. Fig. 2 shows an outside elevation. Fig. 3 represents a front view. Fig. 4 is a top View of the hopper. Fig. 5 shows a side elevation of an end sliding bracket. Fig. 6 shows a section of Fig. 5 on line a a. Fig. 7 represents a side view of one of the middle sliding brackets. Fig. 8 is a section of Fig. 7 on line b b. Fig. 9 shows a fragmentary section through two of the chutes on line y y of Fig. 3. Fig. 10 shows a fragmentary section on line w w of Fig. 9.

The hopperis shown with three outlet-openings (although a greater or less number could be incorporated) and is shown mounted on a truck 0 of a gas-retort-charging machine. The truck consists of the wheels D D, turning with axles D D. Cross-beams G are carried on beams c, which also support the journal-boxes F F F F. In Fig. 1 there are also shown in section the scoops of a retortcharging machine to represent the applicability of my hopper to such an apparatus.

The hopper H is secured to the carriage O by means of the legs H H 11*. The said legs are fastened to the sides of the hopper and abut against the angle-irons H is divided into three compartments h h h of approximately equal volumes, which constitute chutes for discharging the contents. These compartments are proportioned to increase in volume downwardly from their throats, avoiding choking the coal. They are formed by the plates 1) p p, terminating in the curves 17. Plates 1" r r extend from The hopperthe plates 19, and both are secured in place by the brackets 3 3 3. Angle-irons o o to '0 inclusive, strengthen the structure. The compartments are tied at their upper ends with suitable braces 1, 2, and 2. The plate m extends from the front wall of the hopper to give the compartment 72. its proper capacity. The upper ends or mouths of the compartments are side by side, so as to be capable of being simultaneously filled when the hopper is run under a bin. The curves 17 are of large radii to reduce friction and insure an easy discharge and are shaped to also constitute retaining-troughs N N N. The troughs N are formed by the plates n, which extend outward from the plates 7 and are supported on the brackets 29 and 29 They bend down at their outer ends to form the chutes N. Side clips 0 and 0 tie the sides of the hopper and the chutes N. Under and beyond the curved portion of each chute is located a pusher, which carries the coal from the retaining-troughs N and pushes it toward the chutes N, by which the coal is delivered into scoops when they are in proper position to be charged by the coal-hopper. The pushers, of which there is one for each compartment, consist of the curved cover 4, with the sliding brackets 30 and 30, operating under the guides N and extending between the sides 5 5 of the hopper. On the inside of the curved pushers 4 are fastened the brackets 7, which carry the pins 8 for the links 9. Square cross-shafts O extend between the sides 5 5 and are journaled at the ends in the journalbox brackets 10 and 10. The journal-box brackets 10 10 are fastened to the sides 5 5 of the hopper, and the brackets 10 are fastened to angle-irons 23, secured to the sides of the hopper and also carried on the carriage C. Cranks 11 are bolted to the shafts O and are connected to the links 9 by the pins 12. The pins 12 can be placed at different radial distances from the centers of the cross-shafts O by using different holes in the cranks, as 13, so as to be enabled to change the strokes of the pushers and also to obtain different lengths of strokes for the respective ends of each pusher, because it may be desirable for a pusher to have a longer stroke on one end than on the other, the result of which would be by pins 22 to the levers 20, and by means of which through the cranks l1 and links 9 the pushers 4 and stirring-bars 14 are actuated. To the legs H are fastened the guides 24 and 25 to support the handle-bars at the rear ends.

It will be seen that the lever 20 of the lowest chute takes an upward direction from the cross-shaft O, as it would not be practicable to take a downward direction when used on a carriage C, as here represented.

To use the hopper, it is first run under a coal-bin and filled, when it is moved in operative position for charging retorts, and to make the coal issue from the chutes any one of the handles 26, 27, or 28 is moved.

Having described myinvention, I desire to secure by United States Letters Patent, and claim- 1. Ahoppercontaining; compartmentsconstituting chutes terminating in curves of large radii, forming the upper and lower walls of said compartments; troughs extending from said chutes; plates extending downward from the chutes; brackets, connecting the chutes and extension-plates; brackets connecting the troughs and extension-plates; side clips conmeeting the outward ends of the troughs with the sides of the hopper.

6. A hopper H, comprising compartments h, h, 71 constituting chutes with curved outlets 17, troughs N, and chutes N, cross-shafts O, cranks 11 of variable radii secured to the cross-shafts, pushers with covers 4 operating in the troughs N and under the curved ends 17 of the chutes, brackets 7 connected to the pushers, links 9 connecting thebrackets 7 and cranks 11, stirring-bars 14, bracketsl6 connected to pushers; links 15 connecting the said brackets and stirring-bars, levers 20,with handles 26 secured to cross-shafts, handlebars 21 with handles 27 and 28 linked to the levers 20.
